daw/webpack.config.js

/**
 * Build config for the v0.5.0 FSE migration (@wordpress/scripts + webpack).
 *
 * Phase 1 (CSS): webpack now produces the site-wide stylesheet `v4-style.min.css`
 * (the old gulp `build` task). The legacy gulp pipeline still handles the JS bundles
 * for now — those migrate later, as their jQuery-era behaviors get modernized during
 * the template phases (see _claude/notes/upgrade-plan.md).
 *
 * Output layout (output.path = theme root so nothing escapes it):
 *   - JS            → build/[name].js   (src/index.js seed; block view scripts later)
 *   - v4-style      → v4-style.min.css  (theme root — keeps the `style-min` enqueue + font url()s valid)
 *   - other CSS     → build/[name].css
